Key Takeaway
New homeowners in West Texas should verify shutoff valve locations, test water pressure (40 to 80 psi ideal), check water heater age and condition, test water hardness (Odessa averages 15 to 25 gpg), inspect visible pipes for corrosion, and consider a sewer camera inspection before closing. Standard home inspections cover plumbing only at a surface level and often miss hidden issues common in Permian Basin homes.
Why New Homeowners Need a Dedicated Plumbing Inspection
Buying a home in West Texas is one of the largest financial decisions you will make, and the plumbing system is one of the most expensive components to repair or replace if problems go undetected. A standard home inspection covers plumbing at a general level—the inspector runs faucets, flushes toilets, checks for visible leaks, and notes the water heater age. But a general home inspector is not a licensed plumber, and there are critical plumbing assessments they are not equipped or required to perform.
A general home inspection does not include a sewer camera inspection, which means the condition of the underground sewer line from the house to the city main is unknown. It does not include water hardness testing, water pressure measurement with a gauge, or a detailed assessment of pipe materials and their remaining useful life. In a region like the Permian Basin, where hard water at 15 to 25 grains per gallon accelerates corrosion and scale buildup, and where slab foundations and expansive soils stress underground pipes, these are not optional extras—they are essential.
At Resolv Services, we perform comprehensive plumbing inspections for new homebuyers across Odessa, Midland, Andrews, Monahans, Big Spring, and the surrounding area. Our inspection goes far beyond what a general home inspector covers, and the findings can give you negotiating leverage before closing or help you budget accurately for the first year of homeownership.

Locate All Shutoff Valves on Your First Day
The single most important thing to do on your first day in a new home is locate every water shutoff valve. In a plumbing emergency—a burst pipe, a failed water heater, an overflowing toilet—your ability to shut off the water within 60 seconds can mean the difference between a $300 repair and a $10,000 disaster. Do not wait until water is spraying across your kitchen to figure out where the shutoff is.
Start with the main water shutoff valve. In most Odessa homes, this is located in one of three places: on the exterior wall facing the street (usually near the front hose bib), inside the garage on the wall closest to the street, or at the water meter near the curb. The meter shutoff requires a meter key, which you can buy at any Odessa hardware store for $10 to $15. Turn the main shutoff off and on to confirm it works. If it is stuck, corroded, or leaks when you operate it, that is your first repair priority.
Next, locate individual fixture shutoff valves. Every toilet should have a shutoff valve behind the base on the wall or floor. Every sink should have hot and cold shutoffs under the cabinet. The water heater should have a cold water shutoff on top of the unit. The washing machine should have two shutoff valves (hot and cold) behind the unit, typically accessed through a recessed box in the wall. The dishwasher shutoff is usually under the kitchen sink. Test every one of these valves. In older Odessa homes, gate valves installed 20 to 40 years ago frequently seize or fail. Replacing a corroded gate valve with a modern quarter-turn ball valve costs $75 to $200 per valve and is worth every dollar.
Assess the Water Heater, Pressure, and Hardness
Check your water heater on day one. The rating plate on the side of the unit shows the manufacture date, capacity, and model number. Tank water heaters in the Permian Basin have a realistic lifespan of 6 to 10 years due to hard water conditions, compared to 10 to 15 years in regions with softer water. If your water heater is over 8 years old, budget $900 to $1,600 for a tank replacement or $2,500 to $4,500 for a tankless upgrade in the next 1 to 3 years. Look for rust at the base, moisture around fittings, and any corrosion on the T&P (temperature and pressure) relief valve. A water heater that is actively leaking needs immediate replacement.
Test your water pressure with a gauge that threads onto any hose bib. These cost $10 to $15 at hardware stores or we can test it during an inspection. Ideal residential water pressure is 40 to 80 psi. Pressure below 40 psi causes poor shower performance and slow-filling fixtures. Pressure above 80 psi stresses pipes, fittings, valves, and appliances, leading to premature failures and leaks. Odessa municipal water pressure varies by neighborhood—some areas near the water tower run 90 to 100 psi, which requires a pressure reducing valve (PRV) to protect your plumbing system. A PRV installation costs $250 to $500.
Test your water hardness. You can buy a test strip kit for $8 to $12, or we include hardness testing as part of our new homeowner inspection. Odessa municipal water typically tests at 15 to 25 grains per gallon, which is classified as very hard to extremely hard by the Water Quality Association. At these levels, you should expect accelerated scale buildup in water heaters, reduced lifespan for appliances that use hot water (dishwashers, washing machines), mineral deposits on fixtures and glass shower doors, and potential for pipe scale to restrict flow over time. If the previous homeowner did not have a water softener, consider installing one. A whole-house water softener costs $800 to $3,000 installed, depending on capacity and brand. Kinetico, Culligan, and Fleck are the three brands we install most frequently.
Inspect Visible Pipes and Look for Signs of Previous Leaks
Walk every room of your new home and look at every visible pipe, supply line, and drain connection. Open all cabinet doors under sinks and look for moisture, staining, warped wood, mold, or musty odors. These are signs of active or previous leaks that the seller may have cleaned up cosmetically without fixing the underlying cause. Check the ceiling below every bathroom for water stains or fresh paint patches that may be covering previous water damage.
Identify your pipe materials. Homes in Odessa and Midland were built across several decades, and the pipe materials changed over time. Homes built before 1960 may have galvanized steel supply lines, which corrode from the inside and have a functional lifespan of 40 to 70 years. Homes built in the 1970s through 1990s likely have copper supply lines, which last 50 to 70 years but are vulnerable to pinhole leaks in hard water environments. Homes built after 2000 often have PEX (cross-linked polyethylene) supply lines, which are the most durable option for Permian Basin water conditions and are rated for 40+ years.
For drain lines, look for cast iron (dark gray, heavy—common in pre-1975 homes), ABS (black plastic—common in 1975 to 1995 homes), or PVC (white plastic—standard after 1995). Cast iron drains corrode internally and have a lifespan of 50 to 75 years. If your home has cast iron drain lines and was built before 1975, a sewer camera inspection is strongly recommended. Replacing the entire drain system in a typical Odessa home runs $5,000 to $15,000, so knowing the condition before you close on the purchase can save you from an unexpected five-figure expense.
Check under all sinks for the type of supply lines connecting the shutoff valves to the faucets. If you see rubber or vinyl supply lines (often white or gray, sometimes braided with fabric), replace them immediately with braided stainless steel supply lines. Rubber supply lines are the leading cause of catastrophic under-sink water damage we see in Odessa. Braided stainless lines cost $8 to $15 each at any hardware store and take 10 minutes to install.
Sewer Camera Inspection and Outdoor Plumbing Checks
A sewer camera inspection is the single most valuable plumbing assessment you can perform before closing on a home in West Texas. A licensed plumber inserts a waterproof camera into the sewer cleanout and advances it through the entire main drain line from the house to the city connection. The camera reveals root intrusion, pipe cracks and breaks, joint separations, bellied (sagging) sections that trap waste, and the overall condition of the pipe material.
In Odessa and Midland, homes built before 1980 commonly have clay (terra cotta) or cast iron sewer lines. Both materials deteriorate over decades, and many of these lines are now 40 to 60 years old. A sewer camera inspection costs $150 to $300 and takes about 30 to 45 minutes. If the inspection reveals a failing sewer line, you can negotiate the repair cost with the seller before closing, potentially saving yourself $3,000 to $10,000 or more. We perform sewer camera inspections across Odessa, Midland, Andrews, Big Spring, Monahans, Pecos, and surrounding communities.
While you are outside, check every hose bib (outdoor faucet) for leaks, proper operation, and anti-siphon vacuum breakers. Test the irrigation system zone by zone if the home has one, looking for broken heads, leaking valves, and uneven coverage. Check for proper drainage around the foundation—water should flow away from the house on all sides. Improper grading that allows water to pool against the slab is a contributing factor in slab leaks, which are already a common concern in Permian Basin homes due to expansive soils.

West Texas-Specific Concerns for New Homeowners
Buying a home in Odessa, Midland, or anywhere in the Permian Basin comes with plumbing considerations that do not exist in other parts of Texas. Understanding these regional factors helps you budget accurately and avoid surprises in your first years of ownership.
Slab foundations are standard in West Texas. Unlike homes in East Texas or the Midwest that have basements or pier-and-beam foundations, the vast majority of homes in Odessa and Midland are built on concrete slab foundations. This means supply lines and drain lines run through or beneath the concrete, making them inaccessible without specialized equipment. Slab leaks—pinhole failures in supply lines under the slab—are one of the most common and expensive plumbing repairs in the region. Signs include unexplained wet spots on the floor, the sound of running water when all fixtures are off, a hot spot on the floor (indicating a hot water line leak), or a water meter that spins when nothing is running. Slab leak detection costs $150 to $350, and repair runs $800 to $3,000.
Older pipe materials are common. Many Odessa neighborhoods were built during oil boom periods in the 1950s through 1970s. Homes from this era frequently have galvanized steel supply lines, cast iron drain lines, and clay sewer pipes. If the home you are purchasing was built before 1980 and has not had a repipe, budget for the possibility that some or all of the piping will need replacement within the next 5 to 15 years. A full repipe of a 1,500-square-foot Odessa home typically costs $4,000 to $8,000 for supply lines (PEX) and $5,000 to $15,000 for drain lines.
Hard water damage compounds over time. If the previous owner did not maintain the water heater, flush it regularly, or install a water softener, expect to find significant scale buildup in the tank, reduced hot water performance, and shortened appliance lifespans. Check the inside of the dishwasher and washing machine connections for mineral deposits. White crusty buildup on faucet aerators and showerheads is normal in Odessa but indicates that the entire plumbing system is accumulating scale internally.
